用高溫經(jīng)常表示軸承已處于異常情況。高溫也有害于軸承潤(rùn)滑劑。有時(shí)軸承過熱可歸類于軸承的潤(rùn)滑劑。若軸承在超過125℃的溫度長(zhǎng)期連轉(zhuǎn)會(huì)降低軸承壽命。引起高溫軸承的原因包括：潤(rùn)滑不足或過分潤(rùn)滑、潤(rùn)滑劑內(nèi)含有雜質(zhì)、負(fù)載過大、軸承損壞、間隙不足及油封產(chǎn)生的高摩擦等等。 </p> <p> 因此，連續(xù)性的監(jiān)測(cè)軸承溫度是有必要的，無論是測(cè)量軸承本身或其它重要的零件。如果是在運(yùn)轉(zhuǎn)條件不變的情況下，任何的溫度改變可表示已發(fā)生故障。 </p> <p> 軸承溫度的定期量測(cè)可藉助于溫度計(jì)，例如SKF數(shù)字型溫度計(jì)，可精確地測(cè)軸承溫度并依攝氏溫度或華氏溫度定單位顯示。 </p> <p> 重要性的軸承，意味著當(dāng)其損壞時(shí)，會(huì)造成設(shè)備的停機(jī)，因此這類軸承比較好應(yīng)加裝溫度探測(cè)器。 </p> <p> <br /> 浙江ABL角接觸軸承NSK軸承動(dòng)力特性的分析涉及固體接觸的彈性變形與彈性流體動(dòng)力潤(rùn)滑分析及其相互影響修正。</p><div
